Those designated rooms are the following: Basement: room 003 hydrogeological experiments, sediment preparation 2 rd floor: room 308 chromatography and adjacent room 308a room 317 sample preparation for gas chromatography Laboratory building: room 133 spectroscopy (IC, GC, ICP-MS) room 135 chemical analyses room 138 hydrogeological experiments (in cooperation with chair of sedimentology, Prof. Breitkreuz) Laboratory work in all other than the above mentioned rooms is strictly forbidden. 3 Health, safety and fire protection at the workplace 3.1 Emergencies / Responsible persons / emergency numbers Emergency numbers: Police Fire works / rescue service University internal numbers: Safety inspector 2577 (Mr Drees) Fire protection expert 2089 / 2577 Company doctor (Dr. Herrmann) Expert for hazardous substances 3258 (Mr. Drees) Meisser building: Head of the Department 2775 (Prof. Merkel) Secretary 2792 (Mrs. Berg) Competence for the building 2890 (Mr. Böhme) Safety inspector 3224 (Mr. Segler) Head of the Laboratory 3190 (Mr. Dr. Kummer) 1 / 12

2 Information in case of emergency In case of any emergency keep calm, call the emergency numbers, and give the following information: 1. Who calls? 2. What happened? 3. Where did it happen? 4. Are there persons in imminent danger, injured or dead persons? 5. Wait (maybe there are some questions left)! In case of fire consider additionally: 1. Fire-fighting by yourself only if it is possible 2. Inform fire works (number: 0-112), give them the information s above 3. Trigger the fire alarm, if there are no automatic fire detectors 4. Turn off electrical equipment 5. Close the windows and doors 6. Leave the building via the evacuation routes and gather at the meeting point (meadow between Meisser- and Humboldt building) while taking injured persons with you pressing a wet towel against mouth and nose, when there is smoke emission not using elevators For further medial treatment, inform or visit Dr. Wehr or Dipl.-Med. Walther (phone 34751). Report the accident at Mr. Böhme s (Meisser building, room 313, phone 2890). (In case of any accident Mrs. Maja Merz (Meisser building, room 127, phone 2352) is trained in first aid.) 3.2 Instructions According to the German regulations to avoid accidents in laboratories ( Unfallverhütungsvorschrift, Teil: Allgemeine Vorschriften 7 (2)) all persons working in the laboratory have to be informed about possible dangers during their laboratory activities as well as measures to prevent hazardous situations. This introduction to the general regulations has to be done Before starting any work in the laboratory Whenever changing to a different type of work, even temporarily Whenever operating conditions change and at least once a year as a refreshment course 4 Do s and Don ts while working in the laboratories 4.1 General Smoking, eating, and drinking are strictly prohibited in all laboratory rooms. Food is not to be stored in laboratory glassware, and chemicals are not to be stored in food vessels. Jackets and personal gear are not to be stored in the laboratory, but only on designated hallstands, respectively in lockable personal cupboards. Work can only be conducted in the laboratories during official working hours. At any time, there have to be at least 2 persons in the laboratory. Exceptions are only possible after prior arrangement with the laboratory head or his deputy. 2 / 12

3 The security advice sheets have to be consulted before starting any work in a new room. Everyone working in the laboratory especially has to be familiar with the position of fire extinguishers, alarms, showers, eye showers, emergency power cuts, evacuation routes, and first aid kits. Laboratory head, deputy, and special regulations for single rooms are listed on the security sheet for each room. All rooms have to be kept clean and tidy, especially sinks have to be cleaned after use. Windows and doors have to be closed after finishing work for the day, electrical equipment has to be turned off, as long as not marked differently (long-term experiments). Work in the laboratory has to be registered in the general laboratory book (name, activity, duration of activity) which is provided in each lab. Persons can be liable for damages resulting from reckless handling, or neglecting the laboratory rules. 4.2 Laboratory workwear Part of safe laboratory practice involves dressing appropriately (no open shoes, no shorts, etc.). While working with chemicals white coats have to be worn. Further safety means (glasses, gloves) have to be used while handling acids, bases and toxic substances. Neither the university TU Bergakademie Freiberg nor their personal are responsible for damages to clothes or health. 4.3 Glassware handling Glassware has to be in a perfect condition, damaged or broken glassware is to be thrown away, glass fragments have to be cleaned up carefully. The laboratory head has to be informed to care for replacement of broken glassware. While breaking glass tubes or sticks, or introducing glass tubes or sticks in rubber sealings protect your hands with towels. Used glassware has to be cleaned and put back into its designated area. If using a dishwasher, the one who fills and runs it, is also responsible for emptying it. 4.4 Handling of chemicals In general handling of chemical substances requires a prior introduction from and information of the laboratory head. Handling hazardous chemical in potentially dangerous amounts is not to be done alone. While handling acids, bases, or corrosives safety wear must be worn. While diluting acids or bases, always put in first the water and work over a sink or underneath a dust hood. All chemical bottles and vessels have to be labelled clearly (name / initial, chemical, concentration, date). The labelling also includes the common symbols for hazardous substances. Unlabelled bottles with indefinite content must not be in the laboratory in any case. Handling toxic substances requires skilled and trained personal. Toxic substances are stored in a separate cupboard. Consumption has to be registered in the corresponding book for toxic substances. If hazardous gases or fume is to be expected from chemical work, the work has to be done underneath dust hoods. There are two dust hoods in room 135, one in room 133, 3 / 12

4 as well as two mobile ones. Their operation has to be arranged with the laboratory head. Untrained persons are self-responsible to arrange the necessary security briefing before their work starts. The laboratory head has to be informed early enough if chemicals draw to a close. Whoever takes destilled / deionized water has to take care for its remaking. 4.5 Handling of gas bottles For the rooms in the Meisser building (basement and 2nd floor) gas bottles can only be kept inside the rooms in amounts that are consistent with the actual consumption. Excessive storage has to be avoided. Gas bottles have to be secured against falling and heating. If necessary they have to be stored in designated hazardous material cupboards (e.g. acetylene: fire protection). They are only to be transported with suitable aids and generally only with the corresponding security cap. An introduction about handling gas bottles and reducing valves has to be passed before starting to work with gas bottles. For the laboratory building adjacent to the Meisser building a central gas storage unit exists. Storage of gas bottles in the laboratory rooms 133, 135 and 138 is only permitted in rare cases and after prior approval by the laboratory head. 4.6 Handling of mechanical or electrical equipment Mechanical or electrical equipment is only to be used after prior briefing by the laboratory head. Untrained persons are responsible to arrange the necessary security and operating briefing for their work by themselves. The laboratory head has to be informed immediately if any mechanical or electrical equipment is damaged, in order to take care for repair or replacement. 4.7 Work space Works spaces have to be kept clean and tidy. Neither chemicals, nor glassware, nor mechanical or electrical equipment are going to be removed from other persons work spaces. The laboratory head must be informed about long-term experiments, and those have to be labelled accordingly (name, short description of the experiment stating chemicals, media, equipment used, start and scheduled end of the experiment, emergency telephone number). Long-term experiments have to be check upon regularly by the person running the experiment or any representative. Any experiment has to be documented in a personal, numbered laboratory book, which has to be shown to the laboratory head if required to do so. In case of emergency work spaces can be controlled and closed by the laboratory head. If lockable cupboards are available, the laboratory head has a spare key. 4 / 12
